AUTOMOBILE TOOL.

Application filed November 20, 1920. Serial No. 425,511.

To all whom it may concern. 7

Be it known that I, WILBUR J. NUSBAUM, a citizen of the United States,residing at l Vashington, in the District of Columbia, have inventedcertain new and useful Improvements in Automobile Tools, of which thefollowing is a specification.

My invention relates to improvements in automobile tools and especiallyto tools for use with automobiles having a planetary system oftransmission, such as the Ford, wherein the planetary gears for slowspeed. reverse and brake are operated principally by foot pedals, eachpedal being connected to a separate band encircling respectively theslow speed (or clutch) drum, the reverse drum and the brake drunn Thesebands are tightened by the use of the pedals and loosened by the actionof helical springs interposed between extensions of the bands.

his a well known fact among Ford own-- ers and repairmen that therenewing of transmission band linings in a Ford automobile is adiflicult and tedious task. After the bands have been properly relinedand placed in position on their respective drums.

the housing carrying the shafts of the clutch,

reverse and brake pedals. must be replaced.

In replacing this housing it is necessary to compress the three springswhich after assembly keep the bands loose on the drums, and insert thetransmission band projections between the springs and the washers on theshafts. -This operation ismade diflicult be cause of the fact that theheavy housing carrying the shafts must be handled in connection with thespring and band assembly.

The task consumes on an average of two hours of very trying work, for nosooner than one shaft, band and spring is properly assembled and thenext one is under way, the first spring jumps out of position.

The device which constitutes the present invention presents a readymeans of uniformly and simultaneously compressing the three springs,holding them compressed and in such position that the projections of thebands may easily be inserted between the springs and the shaft washerson one side and between thesprings and housing bearings on the otherside. The saving of time is very great and an otherwise difiicult job iseasily accomplished. An addltional ad-' vantage gained through the useof a tool Specification of Letters Patent. Patgnted Aug.

parts which will be hereinafter more fully described and pointed out inthe claims.

The invention will be more fully under-- stood from the followingdescription in connection with the accompanying drawing forming parthereof, in Which,

F igure 1 is a perspective view of the top housing of a transmissioncase of a Ford automobile showing my automobile tool in operation, and Iis an enlarged perspective view 4 of the device, and r Figure' 3 is anenlarged Figure 2 perspective view of a simpler form of t-he'device,embodying the same principles.

Figure 4 is a vertical longitudinal section through the structure shownin Figure 2.

F igu're 5 is a similar section through the structure shown in Figure 3.

Referring to the drawings, 1 represents the transmission cover of a Fordautomobile and 2, 3 and 4 the clutch, reverse and brake pedalsrespectively, with corresponding shafts 6. 7 and S which engage theprojections 9'- of the transmission bands. The pedals cooperate with thesprings 10, in connection with the projections of the bands to tightenor loosen the bands on the drums of the transmission gears.

The tool constituting the present invention includes opposed leaves 1.1which are pivotally mounted, as at 12, upon opposite portions of a body13, which in the form shown in Figures 1 and 2 constitutes a frame; aseries of notches 1-2; is provided in one end of each leaf 11 while theother end portions of the leaves are spaced apart by a spreadingn'ieinber 15. This member can he a cone carried by a screw 16 threadedwithin the body 13 and having any suitable means, such as a head 17, forrotating it. coiled spring 18 orthe like connects the opposed leaves soas to hold them normally in contact with the spreading member 15. Astationaryjaw 19 is extended from the body 13 and has a series ofnotches 2O similar to the notches 14'.

In using the tool, the housing 1 together The spreading member 15 U-shaped, throughthe leaves 11, the ends of thisspring sunie an awkwardor unnatural position. The bands are then removed, rehned and replacedon their respective drums. The

' notched ends of the leaves 11 are then moved spreading member and thecollars 21 on the shafts 6', 7 and 8.

The screw 16 is then operated. to draw the spreading member 15 upwardlyso that the leaves 11 will swing toward each other at their lower ends,thereby compressing the springs 10 and holding them properly spaced fromthe collars 21. With the parts thus assembled the housing, with the toolin position therein, is loweredv into place so that the shafts 6, 7 and8 will become seated in the proj ections 9 of the transmission bands. isthen moved downwardly by the screw 16, thereby allowing the springs10.to expand and also permitting the tool to be withdrawn. The bands arenow properly assembled and the tophousinglof the transmission case canbe'secured and the bands adjusted.

Instead of providing abody such as has been shown at 13, the leaves 11can be pivotally connected to: opposite side portions or a plate 22 asillnstratedni' Figure Tn thiSIfOIIn of ClGVlCQ'iLhG spreading element 23is in the form of a conical nut engaging a stationary screwQ; upstandingfrom the plate 22.
